I am writing this post in order to highlight some of the recent parts of the modern JavaScript that have solved many problems of JavaScript that many JavaScript developers were waiting for.
So without any further chitchat let's get straight into the topic.
Template Strings
Template Strings have made it very easy to embedded variables into the Strings and also working with Strings have become easy as well.
In the following example we can easily use variables into the Strings.
Destructuring
One of my favourite feature of modern JavaScript. This feature allows the developer focused on what instead of how.
Destructuring allows to extract that data that is required to complete or do any specific work.
This feature of JavaScript requires another separate article because there are several types of Destructuring such as Array Destructuring and Object Destructuring.
Let's try to understand Object Destructuring by the means of the following example.
Now What we are doing here is that getusers() will be returning the array os JSON objects that contains the information regarding the users, but we do not to have to completed response and we want only specific things to work with for example the First Name, Last Name and Profession. so by the Object Destructuring we can only receive array of objects having only these properties.
Array.flat()
The Array.flat() method on arrays allow to convert any Dimensional Array into one less dimensional array by default and if to a specific given value as well..
For example we have a 2D Array the Array.flat() will convert that 2D Array into 1D Array and so on.
So Let's have a look at the example of flat() function in action.
There are some other new methods related to Arrays as well such as find(), findIndex(), includes() as well. These methods are also very useful in order to do some common work related to Arrays as well.
Iterators and Generators
The JavaScript has provided us a way to consume the data inside a Data-source one by one until we have not reached to the end of that Data-Source.
Let's get on the example to understand this concept better and have a look at the Iterator and how we can work with it as well.
So these were the some of the most simple and mine favourite JavaScript features that came out recently.
